Hi,

This small set of independent patches tries to fix incorrect
IS_ERR_VALUE macro usage. It fixes most usages leading to errors
as described in [1]. It also follows conclusion from the discussion
[1][2] - IS_ERR_VALUE should be used only with unsigned long type,
signed types should use comparison 'ret < 0'.

The patchset does not fix errors present in net/ethernet/freescale
and soc/fsq/qe drivers - these drivers mixes different types:
dma_addr_t, u32, unsigned long, fixing it properly seems to me more
challenging, maybe maintainers or brave volunteers can look it.

The list of missing fixes:

Can you Cc me the next time on all of the patches? I only got
three of them this time.
